SCREEN FOR CATCl-t-BASINS OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 739,249,datecl.September 15, 1903.

Application filed September 8, 1902. Serial No. 122,463. (No model.)

To ctZZ whom it may concern:

Be it known that'I, WILLIAM H. Woons, a citizen of the UnitedStates,residing at Boston, county of Suffolk, State of Massachusetts,have invented an Improvement in Screens for Catch-Basins or the Like, ofwhich the followthe vicinity.

ing description, in connection with the accompanying drawings, is aspecification, like letters on the drawings representinglike parts.

This invention has for its object the production of a simple andelfective screen for catch-basins and the like to prevent the passage ofsticks, solid refuse matter, or other material into the body of thebasin, the construction of the screen being such that it may be appliedwith equal readiness to existing catch-basins as well as to new ones.

It is well known that catch-basins become filled up and theiroutlet-pipes clogged with all kinds of refuse, and as the outlet-pipe isusually provided with a valve opening out-' ward it will be manifestthat should solid matter become wedged in the valve-opening the valvecannot close and sewer-gas can en ter the basin and be dischargedtherefrom into Catch -basins are frequently made with a contractedclean-out opening or manhole, and the outlet is located in the side ofthe basin nearer its top, so that some water and sediment can collect inthe bottom of the basin to be removed from time to time.

When refuse vegetable or animal matter and,

other solid objects are permitted to pass into the basin, the latter issoon filled and cannot perform its proper office.

In my present invention I have devised a screen of peculiar constructionand adapted to be supported in the basin above its outlet and a shortdistance below its top, the screen permitting the free passage of liquidmatter, but efiectually preventing any solid matter in bulk fromentering the lower part of the basin. The screen is made collapsible orfoldable, so that it can be inserted or removed through the manhole, andit is also provided with a detachable section which can be temporarilyremoved when it is desired to have access to the lower part of thebasin.

The various novel features of my invention will be hereinafterdescribed, and particularly pointed out in the following claims. Figure1 is a vertical central section of a catch-basin provided with a screenembodying one form of my invention; and Fig. 2 is a horizontal sectionon the line 2 2, Fig. 1,

the outlet pipe of the catch-basin being omitted.

lar in cross-section and constructed of brick or other usual material)is provided with a clean-out opening or manhole A, Fig. 1, having acover A the inlet A communicating.

with the gutter, .all substantially of Wellknown construction, the seweroutlet-pipe B having a vertical valve-seat b and a swing- Thecatch-basin A'(herein shown as circuvalve b opening outward. The outletis shown in Fig. 1 as provided with a down As best shown in. Fig. 2,thescreen com prises a plurality of sections or parts, and I have shown acircular screen adapted to conform to the internal shape of thecatch-basin.

In constructing the screen I make a main sec- I tion 01 of reticulatedmaterial, such as strong wire-netting of suitable mesh, secured to asector-shaped rim e, of heavy iron wire or rod like material. Twosmaller and like sections d 01, also of reticulated material, aresecured to rims e e, the said rims having two straight sides at rightangles and a third curved side, as clearly shown in Fig. 2. The sectionsd are located symmetrically with relation to the section (1, so that'aspaceisleft between them, the shorter straight side of each rim e beingconnected by a clip e with the long straight side of the rim 6', so thatthe sections d can be swung relatively to the section (1. To completethe screen, I provide a removable section d of reticulated material,secured to a I have shown a number of pins or lugs a inserted in theside walls of-the basin above the outlet and projecting inward a shortdis tance beyond the walls. These supports may be made in any suitablemanner, and they project far enough to engage the curved parts of therims of the several sections of the screen, holding the latter fiat andin operative position. By an inspection of Fig. 2 it will be seen thatthe sections 01 and d are firmly and securely held in place by the lugsand that the detachable section 01 is held in position by one of thelugs at the outer end of the rim 8 and by the ears a engaging the rim 6.

Any solid matter in bulk is stopped by the screen and held upon it, sothat nothing which could choke or clog the outlet-valve can pass intothe outlet, the material caught by the screen being kept near the top ofthe catch-basin, so that it can be readily removed.

If it is neccessary to get at the basin below the screen, the section dis removed and lifted out without disturbing the remainder of thescreen.

To insert the screen in a catch-basin, the section d is removed and thesections d swung around upon the section d, so that they may be readilypassed through the opening A, and after the screen is in the basin it isopened out and the section d put in its place.

I prefer to make the reticulated material and the rim portions ofgalvanized iron wire, so as to prevent rust or corrosion. The size ofthe mesh and the diameter of the screenwire will depend upon the sizeand character of the basin.

My invention is not restricted to the precise construction andarrangement herein shown, as the same may be modified or rearranged invarious particulars without departing from the spirit and scope of myin- Vention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. A catch-basin having a side outlet and a permanent top provided witha contracted cleanfont opening, a collapsible screen insertible into thebasin through said opening when collapsed, said screen having a sectiondetachably connected with the other part thereof and removable throughtheclean-out opening, and screen-supporting means projecting inward fromthe walls of the catch-basin near the top thereof and between it and theside outlet.

2. A catch-basin, and a screen supported therein below, but near the topof the catchbasin, said screen comprising a plurality ofcollapsibly-connected parts or sections and a section which isdetachably connected with the other and collapsible part of the screen.

3. A collapsible screen for catch-basins and the like, comprising aplurality of sections collapsibly connected, and a detachable section tocomplete the screen-surface.

4. A collapsible screen for catch basins and the like, comprising areticulated sectorshaped section, two like, reticulated sectionspivotally connected with the straight side of the sector-shaped section,and a detachable section also reticulated and adapted to fit between thetwo like sections and provided with means to connect it with thesector-shaped section, the several sections when opened and in conditionfor use presenting a circular, substantially fiat reticulated screen.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
